I rode my SR500 from Europe to West Africa in 1979. The only trouble I had with it was a leaky gearbox seal caused by a jammed chain when something fell off my luggage into the sprocket. I never even got a flat tire through Algeria, Niger, Nigeria and Cameroon. I wonder if I would get as much enjoyment out of an SR400 in the 21st century. I'd like the chance to try because the design of that old single convinced me of it's merits.
